OSAKA, Japan--(BUSINESS WIRE)--Sumitomo Electric Industries, Ltd. (TOKYO:5802)(ISIN:JP3407400005) has developed a new-type coupled multi-core optical fiber suitable for ultra-long-haul transmission, ...

In a world where milliseconds matter and data volumes are exploding, the networks that connect our digital lives are quietly approaching a breaking point. Every time we stream a movie, query an AI ...

A team of Microsoft-backed researchers has unveiled a new type of hollow core optical fiber that promises unprecedented speed and lower latency for the internet. This breakthrough was published this ...

The Azure team’s breakthrough, tested over 1,200 km of fiber, cuts transmission loss to below 0.1 dB/km and expands bandwidth, promising faster, cheaper, and more energy-efficient data networks.

Data travels across the cloud mainly as light via optical fibers made from solid glass. But that light—and thus that data—travels faster through air. “With hollow core fiber, the glass [has] an air ...

DARPA has succeeded in creating hollow-core photonic-bandgap optical fiber, which allows light to travel along its length at around 99.7% the speed of light, or a 30% improvement over conventional ...

A new type of optical fiber filled with nothing but thin air has been found to be particularly effective for carrying out quantum key distribution (QKD), a security protocol that is in principle ...
